My mother recently updated her will and power of attorney, and named my siblings as executors and POA. Why am I being left in the dark?

If it's secrecy and wanting to kerp you in the dark then it is deffiently MONEY!
You should ask your parents about it and if they would mind if you looked over everything. Your Sister is probably now or will start paying herself a certain amount to be Executrix and Power of Attorney.
I hope you get to read everything and maybe even ask if you can be put on both as Executrix and Power of Attorney sharing the responsibility with your sister.
Even if everything is suppose to be divided up between the 3 of you, you may end up with nothing if it's all spent.

Think about changing your perspective. Being POA and executor is alot of work and it sounds like you have already done your share of caregiving. Maybe it was to finally relieve you of so much responsibility for them.

How did you come to see the documents?

How do you generally get on with your sister? Are the two of you on reasonably good terms, ever had any "issues" with one another?

All things being equal, nobody having any particular problem with any other family member, I agree that you might have expected to be included in this discussion. So the question is why weren't you? And the absolutely vital thing is NOT to jump to any conclusions.

The answer is probably along the lines of it was easier, we didn't want to upset you, we wanted to keep it simple, blah blah blah. And you are - aren't you? - satisfied that there is nothing underhand or improper about what has been done. All the same, this is not a good precedent to set when it comes to ongoing communication among the three of you as your parents' care needs increase, and for that reason alone the problem wants nipping in the bud.

So, to repeat - how well do you get on with this sister?

My parents have revised their wills 4 times since 2000. Three of the 4 have happened since 2016, 2017, 2019. I knew what was being said in 2016, my parents asked me to read and make sure the documents said/expressed their wishes-I was POA for HC as I was and had been taking parents to nearly all medical visits-they don't drive now-and been thru many surgeries for both over the years. 2017, the papers changed again-my son became seriously ill, Mom thought I was going to disappear from their life. I have actually done more for my parents in the last 3 years than the 5 years before that. I was removed from all papers. GD was now the health care POA along with other sibling that lives out of state. -she has never been involved with health issues on any level. I was shocked and hurt when I found this out-no discussion no nothing about them planning to make big changes. The estate is no longer going to be divided evenly. House going to lazy brother in addition to his part of whatever is left. Mom seems to have forgotten all this-as she keeps telling me I will be doing XYZ when needed-No not my job any more. Frankly I do not want to be their HC POA. I am for my sister with dementia in a nursing home. I did a lot back in the day before covid for her and as much as I can by phone now. I am still helping my parents but more limits on what they can expect from me. My attitude is not a reflection of the changes they made-my mother was driving me crazy with her abuse and expectation that i do anything she wanted all the time. I do not want to be their POA I do not want to be making painful decisions on their behalf at the end of life. Right now GD will have to do it instead.

I want to thank all of you for all your advice and support. I appreciate all the different opinions and suggestions. I want to add to this discussion, that, no, I do not trust my sister nor do I think she will do the right thing. She is greedy and selfish and doesn't really care about our parents. I, on the other hand, am loving and caring and very selfless. I put others needs before my own. I am sensitive and sentimental but I am also very strong. So, I'm worried and terrified of the future and what is going to happen.

My parents were very old fashioned in their approach to their will. 3 boys, 3 girls--and the executors and POA's have always been the boys. OB died about 8 years ago, so the job falls to the YB's. There are 2 girls older than these brothers, but mother and dad felt that girls weren't capable of doing the job.

I didn't and don't take it personally. Mother has told me for years that her will is an open book, which it is and a boring one to boot. My 'inheritance' is so small, it's not worth mentioning. I'll probably gift it to the YB who has housed her for the last 22 years for no pay whatsoever.

My DH and I could not come to a decision about who should be our executor--in fact, I knew it should be our oldest daughter b/c she is level headed, smart, organized and unemotional. Our son is an attorney who lives in another state and is not the least bit interested in our lives. He is a hot head and if he were 'in charge' as it were, it would fracture my family.

I wanted my daughter, my DH wanted my son to do this, and I am so dang stubborn, I just held out for literally YEARS. He finally caved and now that all is said and done, he sees that the choice of our OD being the executrix is smart and wise.

Yup, Son is upset, but I don't care.

This is not a bad thing. My 94 year old mom has decided to make my only sib and me co-executors and it is going to be a nightmare after she passes. I am prepared to walk away from my inheritance, as my sibling is an all out thief and pirate. Arghhhhh.....

Be thankful you got out of doing any of this. I was POA for mom and am now executor. For several years I took care of her finances. I set up online stuff to automatically come out of her account but the odd expenses would sometimes not get paid on time because she got the mail in and would forget to give them to me. After a while she realized that she could not do it any longer and gave me all the mail. I hired and fired caregivers, made all doctors appointments and took her, monitored her medical records and made sure she ate. This is what the POA will be doing. When she died, I got the task of executor. Her estate had to go to probate and that has been the huge pain. Due to Covid, it is harder to make appointments to do anything. Most of the stuff requires an in person appointment. There has been huge amounts of paperwork and lots of waiting for things to come in by mail. Notifying the heirs has even been challenging. My sister died a few years ago and two of her children are living in RV's traveling the country and do not have permanent addresses. Be glad you get to sit back and collect inheritance but offer to help sort through stuff when the time comes. I spent multiple days just going through her papers to find what I needed.

Don't assume your parents are being underhanded nor your siblings. My mom divided up responsibilities among myself and my 2 sisters: I get medical POA, sister emotionally closest to mom got financial POA, and most emotionally distant sister got executor of will. I'll end up being caregiver since mom moved close to me unless a sister moves from Illinois to Florida. Your siblings may feel weird that you don't have these or are concerned about being left out of decisions and this may the the "thing" mom hopes will bring everybody together.

I agree with Ann, there is a lot involved in being the POA and an Executor. Be glad you have not been given the tasks. And I would not be the Caregiver if I didn't have the POA for Medical and Financial. There are stories on this forum when one child is doing the Caregiving and the POA will not release enough money to care for the parent. Or the POA has taken all the parents money to better themselves and made it hard to get Medicaid when needed.

Please, do not take on the Caregiving fulltime without some guarantees in writing drawn up by a lawyer. Best thing if ever asked to be a Caregiver fulltime , is to say " Sorry, I can not take care of anyone without having a POA. Its not fair to ask me to do a job without having the ability to get to finances or deal with things involving them when needed or be able to talk to Doctors when I am doing the caring."

There are many reasons why your siblings did this. One, is to protect their inheritance. Seems that siblings get closer when a parent starts showing signs of decline. And parents just go with what they say. Just want to control that money. Well, it will go fast if Mom needs 24/7 in an AL or NH. Don't you become that 24/7 care because u will be used.

If you are not designated POA or executor, it may feel as though you were denied some benefit or honor that the designees have gotten and you have not.

Not so in my situation. As one of two independent POAs with equal “power” the other took whatever he valued from the family homestead and moved 1,000 miles away.

As luck would have it, I love our care recipient dearly and do what I can to offer her a peaceful and safe level of care. The other POA writes a check once a month and otherwise ignores her.

No “honor” here.

Unless there are hidden assets, let it go. It is by no means worth feeling bad in any way about.

I write this with the intent of explanation, not of criticism or to add to your concerns.   But the fact that you do feel you should be involved may be the very  reason why your mother chose not to involve you.  

There may be other reasons that we or you may never know, but they may relate to confidence in your ability to handle the tasks, or to keep them private, or to interact well with your siblings.  

Or perhaps it's exactly the opposite:  your parents may feel that you've extended yourself over the years, and want to give you an opportunity to enjoy them now and after they pass w/o having to deal with the end of life and legal issues. 

Try instead to focus on the fact that she's taken care of end of life situations, and be happy that she's presumably found a solution to address them.   And cherish her for what and who she is; these times will never be repeated, you'll never have another chance, so focus on maximizing the positive aspects of your parents' remaining time and the fact that the siblings are involved, even if they haven't been for years.

Imediately stop helping mom out.  If siblings ask you, tell them yo need to be paid.  Or they can hire someone else

Count your blessings and let them have it all. You are finally free.

Are you concerned that your sister will pay herself for helping to take care of your parents, which you have been apparently been doing since before you sister moved closer? And what about your brother. How does HE help?

Is there a chance that you are going to be the main caregiver with no compensation? Your mother wants to split everything three ways, but does she also feel that way about caregiving? She should. Or else the one(s) who are doing the caregiving should get compensated, when they are doing it.

Your guess is as good as anyone else as to why parents do what they do.

It’s done. You can’t change how she arranged it. It may be disturbing to you.

You may be questioning it but I am afraid that you must accept that these are her decisions and you have no other choice but to go along with it.

My parents never discussed their decision to make my brother (middle child; I'm the eldest) their POA and executor. All three of us were on their HC proxies.

This is your parents' decision to make and they owe NO one an explanation.

My father @ 70 is in the process of doing this. He has all the basics done.

he asked us 3 sisters what part we wanted or if he had any material things we wanted. Separately , but then we the sisters talk be hind his back about him ( yes he knows, we tease him about plotting for him and against😂 him)

when he finally made up his mind of whom he wanted to do what he called the middle sister to set up a conference call, so he could go over all of it, to make sure it was ok with us. He did it logically and thoughtful to are personal strengths.

I thanked him for doing it and his answer was my father never did this for me and it was a painful mess to go through, I don’t want that to happen to the sisters( yeah he started calling us the sisters after moms stroke)

anyways if your mother is of sound mind this was a thoughtful thing she did, she just screwed up the delivery, forgive her and be thankful it’s done.

The person to ask is your Mother. She may have her reasons and be perfectly willing to discuss them with you. She may have chosen the person she feels best understands her wishes for end of life care; she may have chosen a person she feels is more competent to handle keeping records and such. We all have our special talents. I don't understand the secrecy either, but I am not the one to ask about it. I would simply say "Mom, I don't understand the secrecy around choosing your POA and executor and just not discussing it with me as one of the siblings. It hurt me to be so out of the loop." Asking is usually the best solution to getting an answer. I did this stuff and it isn't easy and it isn't fun, and I wish I had had another sibling to do it in all truth, but I didn't. I learned a lot, but as I said, it wasn't fun stuff.

Your mother really wasn’t obligated to discuss her will with anyone. And as far as the POA, she wasn’t obligated to discuss that with anyone except those she wanted to designate as her POA. Wills and POA are both things that don’t require a family discussion & should be done by your mother’s own free will. I understand you feel left out but your mother didn’t do anything wrong, she doesn’t have to discuss these with anyone. There is only an issue here if your mother isn’t in her right mind. And if that’s the case, she shouldn’t be changing anything.
